Test of Coal Slime Pumping by Single-Screw Pump

Abstract:

Previous research on thick pastes such as coal slime was using two-cylinder piston pump as power equipment.Since the pressure fluctuation was big,flow measurement was not that accurate. In order to solve the problem, this paper will presents a feasibility study on conveying coal slime by single-screw pump. We used a single-screw pump as power equipment which conveying the coal slime with mass concentration of 64.5%-67.5% . Furthermore, we measured flow rate by self-developed flow meter and completed four groups of test. Through the data such as pressure, flow characteristic obtained from the tests, we have summed up the maximum mass concentration,pressure and flow rate.The results demonstrate the feasibility of conveying coal slime by single-screw pump.The original experimental data and the processing results conform to the theory of law.This paper provides the useful reference for the application of single-screw pump in the field of coal slime pumping.
